不同鸡种及不同产蛋周龄鸡蛋营养成分比较分析
目的比较不同鸡种及不同产蛋阶段所产鸡蛋营养成分的差异。方法在相同条件下饲养海兰褐鸡、苏禽青壳鸡、仿土蛋鸡,比较产蛋前期(21周)、中期(43周)、后期(67周)所产鸡蛋的营养成分及矿物元素含量。结果不同鸡种所产鸡蛋的粗蛋白含量差异不显著(P〉0.05);海兰褐鸡蛋的干物质、粗脂肪、胆固醇、磷脂、磷、铁、硒等含量均显著小于仿土蛋鸡蛋和苏禽青壳蛋(P〈0.05),仿土蛋鸡蛋和苏禽青壳蛋二者间差异不显著(P〉0.05)。产蛋前期鸡蛋的干物质含量显著低于产蛋中、后期(P〈0.05);仿土蛋鸡和苏禽青壳产蛋前期鸡蛋的粗脂肪含量显著低于产蛋中、后期(P〈0.05);产蛋前期鸡蛋的胆固醇和磷脂含量显著高于产...

Summary: | 目的比较不同鸡种及不同产蛋阶段所产鸡蛋营养成分的差异。方法在相同条件下饲养海兰褐鸡、苏禽青壳鸡、仿土蛋鸡,比较产蛋前期(21周)、中期(43周)、后期(67周)所产鸡蛋的营养成分及矿物元素含量。结果不同鸡种所产鸡蛋的粗蛋白含量差异不显著(P〉0.05);海兰褐鸡蛋的干物质、粗脂肪、胆固醇、磷脂、磷、铁、硒等含量均显著小于仿土蛋鸡蛋和苏禽青壳蛋(P〈0.05),仿土蛋鸡蛋和苏禽青壳蛋二者间差异不显著(P〉0.05)。产蛋前期鸡蛋的干物质含量显著低于产蛋中、后期(P〈0.05);仿土蛋鸡和苏禽青壳产蛋前期鸡蛋的粗脂肪含量显著低于产蛋中、后期(P〈0.05);产蛋前期鸡蛋的胆固醇和磷脂含量显著高于产蛋后期(P〈0.05),产蛋后期显著高于产蛋中期(P〈0.05),不同产蛋阶段鸡蛋的粗蛋白、磷、铁、铜和硒含量差异匀不显著(P〉0.05);不同鸡种在不同产蛋阶段所产鸡蛋的钙、镁、锌、锰等含量存在一定差异。结论青壳蛋和仿土鸡蛋营养成分要优于海兰褐鸡蛋,初产蛋除了磷脂含量较高,其他营养成分基本相同。 |

Methods Under the same conditions, the Hy-line brown, Suqin green and Fangtu were fed, the nutrient compositions and mineral elements content of laying early phase (21 weeks), middle phase (43 weeks) and later phase (67 weeks) were compared. Results There was no significant difference in the amount of crude protein produced by different layer breed eggs (P〉0.05). Dry material, crude fat, cholesterol, lecithin, phosphorus, iron, and selenium of Hy-line brown egg were significantly lower than those of Fangtu and Suqin green eggs (P〈 |
